If you think its spyware, get Adaware. It's a spyware remover program and its free! And computer cops is a good site/forum for computer issues with spyware and stuff. Google for Computer Cops.
It also might be that your computer is just too full of useless shit. Try uninstalling things you dont need/use anymore.
And get HiJack This. It is a very good program. It basically tells you all these different files on your computer. It's kinda hard to explain exactly what it does, but it is a really good program, and I think everyone should get it, it really comes in handy. If a file looks suspicious, you can simply check the little box next to it, and click Fix Checked.
BE CAREFUL WHAT YOU DELETE THOUGHHope this helps
